Describes a study in which preschool children, enrolled in a Head Start Program in Texas, tested computer-assisted instruction facilitating visual discrimination. The study, in which a TRS-80 Model III displayed alphabetical characters, showed that four-year-olds are able to learn simple visual discrimination tasks from a computer. (JJD)

Children were individually administered the Matching Familiar Figures (MFF) Test and the Haptic Matching Task. Impulsives received either reflective scanning strategy training or control procedures and were retested. Visual training decreased errors only on the MFF and increased latency on both tasks. Haptic training decreased errors and increased…

Prekindergarten children were given a perceptual discrimination task using letterlike forms and their transformations. The magnitude of the relation to subsequent achievement in reading varied according to the difficulty of a transformation. More easily discriminated transformations were associated with higher correlations. Patterns were similar…

In two experiments, a short-term recognition memory task that varied the number of letters distinguishing target and comparison stimuli was used to assess the ability of prereaders and beginning readers to utilize graphic information in a three-letter graphic pattern. (HOD)

Procedures for programing computers to deal with handicapped students, problems in selective attention, visual discrimination, reaction time differences, short term memory, transfer and generalization, recognition of mistakes, and social skills are discussed. (CL)

The purpose of this study was to provide a task on which subjects could indicate their preferences for linear or painterly art work and to determine if such preferences are related to some traditional measures of cognitive/perceptual style, chosen because they appear to relate to whole/part perception.

Letter pairs that could not be distinguished by learning disabled children were presented using an acquisition-reversal learning paradigm. Relevant external stimuli facilitated discrimination; in reversal, the cues were irrelevant. This technique facilitated learning, as well as retention four days later. (Attentional deficits are discussed). (GDC)

Twenty children, aged 7-12, with severe visual impairments completed a series of visual tasks requiring interpretation, analysis, manipulation, and visual motor coordination. Findings are discussed in terms of total performance, individual task performance, performance of younger versus older children, and performance of good versus poor readers.…

Two experiments studied whether altering an auditory stimulus' rate of change affected infants' fixation of changing visual stimuli. Results demonstrated that infants exposed simultaneously to auditory and visual stimulation showed a reduced tendency to fixate on relatively more visually stimulating events. Heart rates also accelerated during…

Students explore three-dimensional properties by creating red and green wall decorations related to Christmas. Students examine why images seem to vibrate when red and green pieces are small and close together. Instructions to conduct the activity and construct 3-D glasses are given. (MDH)

Children and adults performed a divided attention task and two selective attention tasks with shapes that were either spatially integrated or separated. Results indicate that integrated stimuli are initially perceived as wholes, and separated stimuli as features, at all ages. (BC)

This brief report attempts to resolve the claim that infants preferentially attend to continuous variables over number [e.g. Psychol. Sci. 10 (1999) 408; Cognit. Psychol.44 (2002) 33] with the finding that when continuous variables are controlled, infants as young as 6-months of age discriminate large numerical values [e.g. Psychol. Sci. 14 (2003)…

To steer a course through the world, people are almost entirely dependent on visual information, of which a key component is optic flow. In many models of locomotion, heading is described as the fundamental control variable; however, it has also been shown that fixating points along or near one's future path could be the basis of an efficient…
